How do you figure?
Takara reissued Soundwave back in the day, and Soundblaster shortly after.
Hasbro recently reissued him.
And Takara/Tomy is now restarting the reissues (i think).
So depending on if you collect the Hasbro and/or Takara stuff, and not counting Soundblaster, this would be the second, or third, time he's been reissued.

Yeah Encore is Takara, aka won't be available retail in North America. As for Soundwave, he is a reissue of the original (non-protruding door, buttons on face not one big piece). The TRU exclusive Soundwave was a reissue of the Soundblaster mold in original Soundwave colours.
